IMPROVEMENT IN KNlFE-SHARPENERS.

Specification forming part of Letters Patent No. 205,077, dated June 18,1878; application filed April 27, 1878.

To all whom it may concern:

Be it known that we, DANIEL GUNDELFIN- GER, J r., and ANDREWGUNDELFINGER, of Jefferson City, in the county of Cole and State ofMissouri, have invented a new and valuable Improvement in Knife-Sharpeners; and we do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of longitudinal verticalsectional View of a stove-top, showing our method of attaching aknife-sh arpener. Fig.2 ais plan view of a stovetop, showing the same.Fig. 3 is a modification of the same, showing the application to oldStoves. Fig. 4 is a sectional view taken through the line at a: of Fig.3.

The nature of our invention relates to devices for sharpening knives;and it consists in novel means for attaching the same to top plates ofcooking-stoves, as will be hereinafter more fully set forth.

The annexed drawing, to which reference is made, fully illustrates ourinvention.

A represents the top plate of an ordinary cooking-stove, in one edge ofwhich is formed an opening, with a box or holder, B, projecting downwardbelow the stove-plate. Across the bottom of the box B are two plates orcrossbars, 0 O. This box with cross-bars can all be cast with thestove-plate.

In the box B is inserted a bar, D, of emery,

steel, or other suitable sharpening material,

which is adjusted upward, as may be required, by means of screws a apassed through tapped holes in the cross-bars 0. By this means aknife-sharpener is obtained which is always handy and ready for usewithout any trouble of fastening in place and removing again.

This form of our invention is specially intended to be applied in themanufacture of new stoves.

For old stoves we provide a holder, F, in which the sharpening-bar D isheld, and said holder fastened by screws 12 b to the edge of the topplate A of the stove.

The advantages of our invention are numerous and too obvious to need tobe enumerated.

What we claim as new, and desire to secure v.by Letters Patent, is-

1. The combination, substantially as hereinbefore described, of a topplate of a stove with holder for supporting a knife-sharpener andmechanical means for securing the same.

2. A top plate of a stove provided with a cavity or holder forsupporting a knife-sharpener, and an adjusting device, substantially asdescribed, and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
